sub receiver

[n8ws]

I have lost my sub reciever and can not find the menu that I changed to make that happen. can anyone tell me what I did wronG and help me get my sub receiver back. what I see now in the B vfo is the time, date,  3 zero's, 13.4v, etc etc.
Thanks in advance I know I am going to feel stupid after I find out what I did wrong.
